A Bflap (a homonym of the ZEI verb "to come") can be used to express affirmation, negation, possession, and existence. There is no direct correspondence of a Bflap in Farsi and appears to be unique to ZEI. Ten native signers/fluent users will be recruited for this study. Recruitment was centered in the following Iranian cities: Tehran, Isfahan, Shiraz, Tabriz, and Mashhad. My first hypothesis, in affirmative and negative utterances, Bflap will be sentence-final accompanied by a downward head nod or head raise. My second hypothesis is that a Bflap can be used to express sentential possession (e.g., "have" in English), but it is not clear how it is different from a Bflap used in affirmative and negative utterances. Determining the usage of Bflap will help further the linguistic field specializing on verbs with both existential and possessive meanings, or in other words, copulas with semantic and grammatical features similar to the possessive verbs. In addition, Bflap answers to yes/no questions in ZEI may reveal an underlying grammatical structure. Finally, using Bflap as an imperative may demonstrate sociolinguistic context.
